Babies, babies everywhere! The latest addition to the Hollywood brood is little Otis, the newborn son of powerhouse couple Olivia Wilde and Jason Sudeikis. The 30-year-old reportedly gave birth on Sunday. A twitter announcement followed not long after. She posted a black and white snapshot of herself, snuggling with the tiny newborn.

Congratulations to the new parents!

“Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building),” tweeted Wilde, who has starred in films including Rush and Her.

It has been confirmed – Otis is a cute one. Well, at least the parts of him visible in the picture, which to be fair, contains mostly blanket.

Wilde and 38-year-old Sudeikis – a Saturday Night Live veteran – got engaged in January 2013. The two stars are currently Manhattan-based and have been together since 2011.

Wilde’s pregnancy may be over, but the actress says she enjoyed her time as a soon-to-be mom and even loved flaunting her baby bump. “I just thought, ‘Oh, I’m going to hide this forever.’ But I ended up getting kind of excited to show the bump as a badge of pride,” Wilde says in the May issue of Lucky magazine.

Well, it’s hard to argue with that logic. Beyond the excitement, however, Wilde says that pregnancy has drastically changed her outlook on life. “Pregnancy does shed away all of the bull—. It gives you more empathy because you look at everyone and you think, ‘You were a baby!’” Wilde explains.

She adds, “Pregnancy brings you into this sort of commune — you feel connected to women in a way that you never have.”

So in conclusion… long live the sisterhood? Congratulations to Wilde and Sudeikis and of course to little Otis for, you know, leaving the building.
